Oct 28 (Reuters) - CBOE Holdings Inc, the operator of the largest U.S. options exchange, reported a 40 percent fall in quarterly profit, hit by lower revenue from transaction fees and acquisition-related costs.

Chicago-based CBOE said on Friday that net income allocated to common shareholders fell to $40.28 million, or 50 cents per share, in the quarter ended Sept. 30, from $67.22 million, or 81 cents per share, a year earlier. (Reporting by Sruthi Shankar in Bengaluru; Editing by Ted Kerr)
